Trader sentiment clusters around 18-19°C (61% combined implied probability) for Beijing's March 23 high, driven by the latest ECMWF and GFS ensemble forecasts converging on mild advection from southern air masses amid weak frontal influences. Recent model updates show slight cooling from yesterday's runs due to increased northerly winds and partial cloud cover, narrowing the spread between 18°C (34%) and 19°C (27%) while sidelining 20°C (17%). Differentiating factors include Beijing's urban heat island effect boosting afternoon peaks by 1-2°C above rural stations, historical late-March norms of 14-16°C upended by this year's early warmth, and diurnal uncertainty—max temps typically hit 2-4 PM local time. Upcoming hourly observations from CMA stations will sharpen resolution as traders monitor for any surprise inversions.
